OVERVIEW OF THE SILICONE RUBBER

Silicone rubber’s special features such as “Organosiloxanes Polymer” has beenoriginated from its unique molecular structure that they carry both inorganic andorganic properties unlike other organic rubbers. In other words, due to the Si-O bondof Silicone Rubber and its inorganic properties, Silicone Rubber is superior toordinary organic rubbers in terms of heat resistance, chemical stability, electricalinsulating, abrasion resistance, weatherability and ozone resistance etc...

With these unique characteristics, Silicone Rubber has been widely used to replacepetrochemical products in various industries like aerospace, munitions industry,automobile, construction, electric and electronics, medical and food processingindustry. Recently, these scopes of silicone application have been expanding at agreat speed by the demand of industries that want more reliable elastomer.

Main Characteristics of Silicone Rubber:- Excellent High and Low Temperature Resistance. - Excellent Electrical Properties. - Physiological Inertness. - Excellent Weatherability. - Oil Resistance. - Flame Retardant.

GENERAL PROPERTIES

1. High bonding energy

Silicone rubber has siloxane bond (Si-O) of molecular structure as the main chains. Whilecarbon bond, C-C, carries 84.9 Kcal/mol, siloxane bond carries 106.0 Kcal/mol It showsthat siloxane bond has greater capacity and stability. As a result, silicone rubber has betterheat resistance, electric conductivity and chemical stability than any other ordinary organicrubbers. Siloxane bond’s energetic stability is secured due to sharp difference between Siand O in terms of electro-negativity making Si-O to be closest to ionic bond.

2. Low intermolecular force with spiral structure

With its coi l shaped spiral structure and low intermolecular force, si l icone(dimethylpolysiloxane) is highly elastic and compressible. Furthermore as methyl groups arelocated in the outside of coil structure, they are free to rotate on its own. As a result siliconerubber has outstanding water repellency and contact resistance.

HCRHIGH CONSISTENCY SILICONE RUBBER

Silicone Rubber is classified into HCR (High Temperature Vulcanization) and RTV (Room TemperatureVulcanization) by its curing temperature. Also, HCR is divided into Millable Type Silicone Rubber andLiquid Type Silicone Rubber by its degree of polymerization.

Millable Type Silicone Rubber.

Millable Type Silicone Rubber is composed mainly of Polyorgarnosilioxan(Silicone Polymer) and Silicawith various additives to grant diversified characteristics. We call this stage for Silicone Rubber as“Base Compound”. Then this “Base Compound” is catalyzed, pigmented with roll and cured by pressmolding and extrusion etc...

Due to its status, Millable Type Silicone Rubber is also being called as “HCR (High Consistency SiliconeRubber)” in the market.

Heat Resistance

Heat resistance of silicone rubber isthe one of its most excellent propertiesand provides the basis for its creation. Si l icone rubber is far better thanorganic rubbers in terms of heatresistance. At 150 , almost no alterations of properties take placethat it may be used semi permanently. Furthermore, silicone rubberwithstands use for over 10,000 consecutive hours even at 200and, if used for a shorter term, it may also be used at 300 aswell. Boasting this excellent heat resistance, silicone rubbers arewidely used to manufacture rubber components and parts used inhigh-temperature places.

Cold Resistance

Cold resistance of silicone rubber isthe finest among organic rubbers. Itprovides a critical reason behind thecreation of silicone rubbers. Naturaland ordinary rubbers demonstratesignificant changes in formation depending on temperatures. Theybecome soft at high temperatures and hard at low temperatures sothat they may not be able to used any more. While other organicrubbers may only be used up to -20 or -30 , silicone rubbermaintains its elasticity between -55 and -70 . Some of theproducts even withstand temperatures as extremely low as under -100 .

Weatherability

Silicone rubber has superb ozoneresistance. Due to corona-dischargedozone, other organic rubbers becomesoften at a higher speed, but siliconerubber is rarely affected. Furthermore,even long-term exposures to UV rays, winds, or rain siliconerubber's physical properties will not be changed substantially.

Electric Properties

Sil icone rubber is being used forinsulat ion materials at hightemperature with its superior insulationproperties. It is particularly known forwide range in temperature and volumeresistance between 1014 cm and 1016 cm. Silicone rubberexperiences lowest change in performance in wet condition and isthe best fit for being used as insulation materials. By adding specialconductive fillers, conductive silicone may also be manufactured. Inparticular, silicone rubber is strongly resistant against coronadischarge compares to others, while being widely used forinsulation purposes in high voltage environments.

Electric Conductivity

Conductive si l icone rubber is acompound comprising conductivematerials such as carbon black, silverand copper. Depending on the type ofsilicone rubber, they range in resistancelevel from a few cm to 103 cm. One of the properties is that itselectr ic propert ies are not much affected by variance intemperatures. No rubber materials are not found yet to match theelectric properties of silicone rubber over 200 . Conductivesilicone rubber is also being used for keyboard interfaces, antistaticparts, and shield materials for high voltage cables.

Radiation Resistance

Compares to other organic rubbers,ordinary (dimethyl) silicone rubber hasno special performance in terms of antiradiation. However, methyl phenylsilicone rubber adopting phenyl groupin polymer molecules does have radiation resistance to be used forcables at nuclear power plants and connectors.

Properties of Silicone RubbersHIGH CONSIS

06 _ 07

Steam Resistance

Silicone rubber absorbs only 1% ofmoisture even after experiencing longexposure to water without beingaffected in mechanical strength orelectric properties. Generally, siliconerubber does not deteriorate even after having contact with steamunder atmospheric pressure. In high pressure steam over 150°…,siloxane polymer is cut off and rubber properties decline. Such aproperty may be improved by the composition of silicone rubber,selection of curing agent, and the post curing. Other modifiedproducts are also available with improved steam and boiling waterresistance.

Flame Retardancy

Silicone rubber does not easily burnwhen in contact with a flame, butwould burn out consistently onceignited. However, by adding a smallamount of flame retardant, it maybecome flame retardant and self-extinguisher. Flame retardantsilicone rubbers presently in use would scarcely produce toxic gasduring combustion since they do not contain organic halogencompounds discovered in organic polymers.

Oil Resistance

Silicone rubber is inferior to ordinaryorganic rubber in oil resistance atroom temperature. However, forautomobiles or aircrafts that requirehigh temperature resistance, i tdemonstrates higher performance. Even when in contact withautomobile oil, silicone rubber does not inflate significantly byreason of swelling. It swells in non polar organic compounds suchas benzene, toluene, and gasoline. But its materials do notdisintegrate or dissolve unlike ordinary organic rubbers. If solvent isremoved, it would be restored to the original conditions.

Non toxic

Silicone rubber is physiologically inert,and is thus used for baby nipple andstoppers in medical appl ication.Si l icone rubber is also very idealelastomer for making swimming capsand goggles.

LSR

Applications of liquid siliconeLSR is a material suitable for numerous uses from automobiles,spaceships, high-voltage insulators to sculptures, baby products, etc.Copying machine roller / High-voltage insulators / Keypads / Anodecaps / Connector seals / Diaphram & valves / O-ring, Gaskets & Seal /Diving mask & snorkels / Baby nipple / Wire seal / Gromet

Supply capacity and container sizeBoth A and B are supplied. The inside diameter is as follows.20KG : 282mm ( Can ) 200KG : 572mm ( Drum )

What are manufactured for injection molders in general can be used.

StorageLSR should be stored in a cool and dark place with good ventilationand no direct sunlight. Please do not forget to close the lid after using it.With the lid closed and in the normal temperature range, it can beused with stability for 6 months (in case A and B are not mixed). Makesure to close the lid after use. Also the drum is recommended to beused as soon as possible after opening.

Pot lifeIf the mixture is inside of a cold mixer and injection molder at themixture ratio of 1:1, it can be used for up to 3 days. The new oneshould be supplied from the 4th day.

- If liquid A and liquid B are mixed, it can be stored in a cool and darkplace for up to 72 hours. However, it should be used as soon aspossible.

- As the pot life is subjected to change depending on storageconditions, a close attention should be paid.

Process1. LSR, packed in 20kg or 200kg, is supplied in types of A and B

for easy use. 2. After the dispenser pumps liquid A and liquid B, they are

transported to the static mixer.3. While they are transported to the static mixer, additional

components can be added. 4. Curing takes place within a few seconds between 170 ~230

Caution1. In order for curing not to happen before LSR enter the mold, the

temperature of the nozzle and cylinder should be lowered toabout 20 .

2. Demolding what is cured at an extremely high temperature(above 200 ) can produce volatile materials. It is recommendedto use a system which will remove them.

Post cureMost of silicone rubbers are to have the best properties aftercuring. Compression set, however, can increase in case of post-curing at 200 . At this temperature, a fire can break out due to an emission of thevolatile siloxane. Thus, fresh air should be supplied into the post-curing oven for secondary hardening (100 liter of air per 1kg ofsilicone rubber)

Linear shrinkageLinear shrinkage differs depending on the thickness. As thethickness decreases, linear shrinkage increases, and vice versa. Italso differs depending on the curing temperature. At a highertemperature, linear shrinkage usually increases. Linear shrinkage is a factor which must be considered in designingthe mold. Take LSR-200/50. At 171 and with the thickness of 2mm, itslinear shrinkage is as following.

Non Post-cured 2.7% 0.5%Post-cured 3.5% 0.5%

Compatibility with other substancesThe LSR catalyst, which is cured by addition reaction, cannot becured or can be incompletely cured due to many substances. Theabove phenomenon is possible to happen with such substancewhich are the rubbers cured by sulfuric or organotin compounds,the substances cured by amin, amide, azide, and so on.

LIQUID SILIC

LIQUID SILICONE RUBBER

LSR is Liquid Type and High Temperature Vulcanization Silicone Rubber. LSR differs from MillableType Silicone Rubber and RTV (Room Temperature Vulcanization) by its degree of viscosity and curingtemperature.

LSR is perfect rubber material for automated injection molding due to its excellent liquidity. Also, LSRis ideal for complex molds, demanding design and tolerance because it can be easily filled almostevery complex part of a mold.

LSR also does not generate volatiles or residue during the curing process and it makes LSR possibleto be used that required inertness for example pacifier, diving mask, medical tube, snorkel andbakeware.

ROOM TEMPERATURE VULCANIZATION

HRS RTV 2K is fire-stop material and designed based on Silicone Rubber’s unique characteristicssuch as high temperature resistance, flame retardant, sound-proofness and air-tightness. HRS RTV2K is in two parts and the mixing ratio is 1:1.

Once the two parts mixed, the mixture is to be blown and cured two or three times within 1 ~ 5minutes and stiffens to become a closed cell sponge-type elastomer.

Now, HRS RTV 2K is used as fire-stop material for skyscrapers, hotels, department stores, nuclearpower plant, thermal power plants, chemical plants, refineries where the demand for a perfect fireproofsealing material is on the rise. Also, HRS RTV 2K Foam effectively seals the opening of buildings toprotect human from harmful gases.

What is the silicone RTV foam?It is Silicone Foam blown and cured at normal temperature. It is designed to make use of the original properties of silicone resin mainlycomposed of Silicon such as thermal resistance, fire retardance, sound-proofness and airtightness. Mixing part A and part B at the same rate makes a sticky liquid. This mixture is to be blown and cured two or three times bigger within 1 to5 minutes and stiffens to become a closed-cell sponge-type elastic body.

1. Excellent fireproof.

The silicone foam, mainly composed of silicone, have shown anoutstanding fireproofness through tests like FS 012, KSF 2842,UL-1479, ASTM E-814, ASTM E-84, etc.

This is because its main component is silicone. The siliconefoam blocks heat. Once it is heated, the air inside the cellexpands and tightly seals the spaces between walls, preventingthe fire from spreading.

2. Excellent gas-tight.

The silicone foam is composed of closed cells. Thus, if heated,it further expands and covers openings tightly, blocking harmfulgases and oxygen. In addition, it is highly soundproof,waterproof and moisture proof.

ERATURE VULCANIZATION

3. Excellent resilience and shock-absorbing

The silicone foam is an elastic body cured into thesponge of a silicone rubber elastic body.

This silicone foam, by maintaining its resilience semi-permanently, completely absorbs shocks, preventscracks from taking place, deals with the thermalexpansion and contraction of construction materials.

4. Easy repai

Whenever repair is needed, only such a part can becut. Thus, additional or secondary works can bedone with easy and a complete sealing work ispossible with later injections.

Works are possible while leaving small pipes andcables as they were.

In case of a fire, no harmful gases are emitted.

When a fire breaks out, the damage from harmful gases is bigger

than that from the flare or high temperature.

The silicone foam is safe, not emitting harmful gases.
